Preserved foods are items that have been treated to prevent spoilage and extend their shelf life. Common methods of preservation include canning, freezing, drying, and pickling. These techniques help maintain the food's flavor, texture, and nutritional value, making it possible to enjoy seasonal produce year-round. Many people enjoy preserved foods for their convenience and variety. For example, jams and jellies are made by cooking fruits with sugar, while dried fruits are created by removing moisture. These foods not only reduce waste but also allow for easy meal preparation, making them a staple in many kitchens around the world.
